The Aztecs, like the Mayans, also had their own version of a built-in chocolate tempering machine in their kitchens. Their machine was made of clay and had a unique design. It consisted of a clay pot with a hollow handle. The Aztecs would heat the chocolate in the pot and then use the hollow handle to stir and cool the chocolate, achieving the desired temper. This ancient kitchen innovation allowed the Aztecs to create rich and velvety chocolate that was used in their traditional beverages and desserts.
